X-Ray Diffractometry of Low-Temperature Phase Transformations in Strontium Titanate
Abstract
The lattice parameters of single-crystal SrTiO3 were determined by x-ray diffraction as a function of temperature from 4.2° to 300°K. In addition to the normal cubic structure three significant regions were found. From 65° to 100°K a tetragonal modification exists (c/a=1.00056), from 35° to 55°K line splitting consistent with orthorhombic symmetry was observed, and at 10°K an anomalous maximum in the lattice parameter vs temperature curve was found which suggested a third structure transformation. In the tetragonal region (at 78°K) various domain configurations were photographed with a polarizing microscope.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
